Spindle optimization (automatic)

Benefits
The automatic spindle optimization function supports you in the following scenarios:
● Controller optimization in the various modes: Axis mode and spindle mode.
To this end, the speed controller, position controller, and feedforward control are optimized.
● Calibration of the following errors for tapping by means of path optimization
● Calibration of the following errors for the axis mode by means of path optimization
The progress of spindle optimization is clearly visible to the machine manufacturer:
● The optimization strategy set for the spindle.
● The suitable default setting of the optimization strategy for the selected use case.
● The mode that must still be optimized and the mode that is already optimized.
● The gear stages that must still be optimized and the ones that are already optimized.

10.4 Spindle optimization (automatic)
The "Automatic servo tuning: Axis selection" dialog shows the
current status of the axes/spindles.
● Selection of the modes to be optimized
● Tapping: Definition of the participating axes and gear stages
● Check and edit the optimization strategy
● Optimization of the individual gear stages or of the axis mode
● Tapping: Calibration of the following error of the axes involved
The "Automatic servo tuning: Axis selection" dialog shows the
time of the optimization for each axis/spindle.
The "Automatic servo tuning: Tapping" dialog (bottom section)
shows which parameter sets are already path-optimized:
not optimized
axis-optimized
path-optimized
The "Automatic servo tuning: Controller data overview" dialog
shows the optimized controller settings for the gear stage and for
the comparison of the original data.
Use the "Accept" softkey to write and save the data.
